ATM IMA Configuration Problem

I have a 2600 with at NM-4T1-IMA. I am trying to bond 2 t1's from Qwest for our DSL hosting. I have the 2600 configured like Qwest's sample config for my router but we cannot get the ATM interfaces to come up. If qwest loops my t1s they come up. What is strange is the moment we remove ima-group command from the ATM interface the t1s come up.

We are running 12.3 (26) and we have atm ATM-IMA card installed as well. Qwest is configured for ima 1.0. I have tried different clock modes on the ima interface and on the ATM interfaces. Qwest is saying they are configured for EFS/B8ZS.

I was thinking that as well. But that that turned out not to be the problem. We had Qwest send a tech to check the NIU. They said the NIU was fine, but ever since the tech touched the circuit it has been running clean. I wonder if the NIU wasn't seated right or something.
